Compiling code with GHC

> I noticed that GHC generates huge executables.
As I recall, GHC only uses shared libraries on OSX. Your executable
probably has a lot compiled in statically. Even though I'm pretty
sure GHC does what it can for dead code elimination, statically linked
executables tend to be largish.
A good bit of that executable size may be GHC's machinery, like the
garbage collector and thread manager.
If you haven't already, and if you're on a unix variant, then you can
probably save some space by stripping the executable:
$ ghc --make hello
$ strip hello
Is space usage critical for you? Try different optimization levels.
Use compression. Eliminate dependencies on large external libraries,
if possible.
I just got used to it.
